Magnetic pumps operate based on magnetic drive technology, which uses magnets to attract ferromagnetic materials. The magnetic properties of non-ferromagnetic materials have little to no effect on the strength of the magnetic force. This allows for power transmission without physical contact through a non-magnetic conductor, known as an isolation sleeve. Fluoroplastic magnetic pumps, diaphragm pumps, and pipe pumps can utilize either synchronous or asynchronous magnetic drive designs. Most magnetic pumps use a synchronous design, as illustrated in Figure 2-13. In this setup, the motor is connected externally via a coupling to the outer magnetic cylinder, while the impeller is attached to the inner magnetic cylinder. A hermetically sealed isolation sleeve separates the two magnetic cylinders, ensuring that the inner cylinder remains isolated from the outer one. This allows the motor’s rotating shaft to drive the impeller in perfect synchronization with the magnetic field.
In contrast, asynchronous magnetic drives, also referred to as torque ring magnetic drives, use a cage-like structure instead of an inner magnet. This design replaces the inner cylinder with a torque ring, which functions similarly to the rotor in an induction motor. As the outer magnetic cylinder rotates, it generates a magnetic field that induces an electromotive force and a secondary magnetic field within the torque ring, causing it to rotate at a slightly lower speed. Since there are no permanent magnets involved in the inner cylinder, these systems can operate at higher temperatures compared to their synchronous counterparts.
